Not gonna lie, I wanted to love this more than I do. The transparency is a little more cloudy than the photos, and the thicker sleeve from the duo set feels bulky if you’re not used to this type of thing. That said, the control part genuinely helps, and for $23 I can’t be too upset. I’ll keep it in rotation but probably won’t reorder this exact set.

The two-piece set is simple, but the clear sleeves fit better and stay put longer than the old one we had.

I bought this for my husband after seeing it mentioned in a forum. Arrived in plain packaging, which I appreciated because we have nosy roommates. He said the smaller sleeve was comfortable right away, but the longer one took a few tries to position without pinching. Now that he’s used to it, it’s become part of our weekend routine. Taking one star off for that learning curve.

I was skeptical because I’ve had clear pieces from other brands that felt tacky or rolled up. These are much smoother, and the transparent look is actually kind of subtle. The slight extension wasn’t obvious visually, but my partner said it felt more natural than he expected. We both noticed we could go longer before he needed a break. I already ordered a second set as backup.
